The experiment was carried out to understand the storability of onion seeds by subjecting to different modified atmospheric storage conditions with different combination of gases like carbon dioxide, oxygen and nitrogen at different concentrations. The experiment was consisted of seed storage of onion (Arka Kalyan) under modified atmospheric storage conditions. There were 15 treatments and the experiment was carried out in Completely Randomized Block Design in four replications. The treatments were T1- 80 % CO2 : 05 % O2 : 15 % N2, T2- 70 % CO2 : 05 % O2 : 25 % N2, T3- 60 % CO2 : 05 %O2 : 35 % N2, T4- 50 % CO2 : 05 % O2 : 45 % N2, T5- 40 % CO2 : 05 % O2 : 55 % N2, T6- 80 % CO2 : 10 % O2 : 10 % N2, T7- 70 % CO2 : 10 % O2 : 20 % N2, T8-60 % CO2 : 10 % O2 : 30 % N2, T9-50 % CO2 : 10 % O2 : 40 % N2, T10-40 % CO2 : 10 % O2 : 50 % N2, T11-50 % CO2 : 00 % O2 : 50 % N2, T12-Atmospheric air, T13-Vacuum, T14-Storage in cloth bag, T15-Cold storage and observations on various enzyme activity were recorded. With an advancement of storage period, various enzyme activities differed significantly due to modified atmospheric storage conditions in all the 12 months of storage irrespective of the modified atmospheric conditions. The seeds stored in Cold storage (T15) recorded maximum dehydrogenase activity of (0.280), amylase enzyme activity of (1.28), catalase enzyme activity of (0.246), superoxide dismutase enzyme activity of (0.900) after twelve months of storage period followed by T1: 80 % CO2 : 05 % O2 : 15 % N2 and seeds stored in vacuum (T13). The lowest dehydrogenase activity of (0.190), was noticed in seed stored in cloth bag (T14) followed by the second the lowest dehydrogenase activity recorded (0.220), α-amylase enzyme activity of (1.80), catalase enzyme activity of (0.156), superoxide dismutase enzyme activity recorded (0.730) in see ds stored in polythene bag with air (T12) after twelve months of storage.
